Abstract
The invention provides a pulverized coal burner structure capable of realizing blending combustion of methanol purge gas. The pulverized coal burner structure enables the methanol purge gas to be applied to the interior of a boiler, and the methanol purge gas and pulverized coal in a burner are completely burnt together so that efficient utilization of the energy sources is guaranteed. The pulverized coal burner structure comprises a pulverized coal burner and a methanol purge gas delivery pipe, and is characterized by further comprising a methanol purge gas release gun; an inlet flange is arranged at the inlet of the methanol purge gas release gun; the outer toroidal surface of the inlet flange is fastened and connected with a connecting flange of the methanol purge gas delivery pipe; the outlet position of the methanol purge gas release gun is located in the lower secondary air nozzle of the pulverized coal burner; a close plate is arranged on the front end of the outlet of the methanol purge gas release gun; air outlets are evenly formed in the circumferential direction of the outer toroidal surface, located at the inner side of the close plate, of the outlet of the methanol purge gas release gun; the air outlets are located in the lower secondary air nozzle of the pulverized coal burner.
Description
Technical field
The present invention relates to the technical field of structures of boiler, be specially a kind of coal burner structure of burning methanol purge gas of mixing.
Background technology
Methanol purge gas is the chemical plant installations of chemical enterprise, because methyl alcohol is synthetic, exist many side reactions, these side reactions to generate a large amount of inert gases and constantly accumulation in system, affect the normal operation of the synthetic operating mode of methyl alcohol, must constantly discharge, this emission gases is called the venting of speeding.The synthetic main component of speeding venting of methyl alcohol is the inert gases such as H2, CO, H2O and CH4, and wherein H2 and CH4 volumn concentration account for 90% left and right.The venting of speeding is generally all discharged by torch burning, both wasted energy, and contaminated environment again, the venting part of speeding reclaims for nitric acid workshop tail gas, and another part is discharged by torch burning, causes every days approximately 2 ten thousand steres to speed to diffuse after venting burning, and the utilization rate of the energy is low.
Summary of the invention
For existing above-mentioned defect, the invention provides a kind of coal burner structure of burning methanol purge gas of mixing, it makes methanol purge gas be used to boiler internal, and the common completing combustion of coal dust in methanol purge gas and burner, has guaranteed the efficient utilization of the energy.
A kind of coal burner structure of burning methanol purge gas of mixing, its technical scheme is such: it comprises coal burner, methanol purge gas carrier pipe, it is characterized in that: it also comprises methanol purge gas air gun, the entrance of described methanol purge gas air gun is provided with suction flange, the cylindrical anchor ring of described suction flange is fastenedly connected the adpting flange of described methanol purge gas carrier pipe, the exit position of described methanol purge gas air gun is positioned at the lower overfire air port of described coal burner, the front end of the outlet of described methanol purge gas air gun is provided with shrouding, the circumferential venthole that is evenly equipped with of outer ring surface of the inner side that is positioned at described shrouding of the outlet of described methanol purge gas air gun, described venthole is positioned at the lower overfire air port of described coal burner.
It is further characterized in that: described venthole is specially mounting hole, and the length direction of single described waist-shaped hole is parallel to the inside center line of described methanol purge gas air gun.
Adopt after structure of the present invention, the outlet of methanol purge gas rifle is arranged in the lower overfire air port of coal burner, with coal burner, be arranged in together the bight of burner hearth, the exit of methanol purge gas rifle arranges shrouding, the circumferential venthole that is evenly equipped with on the outer ring surface of the inner side that is positioned at described shrouding of the outlet of methanol purge gas air gun, described venthole is positioned at the lower overfire air port of described coal burner, methanol purge gas from venthole enters burner hearth forms tangential firing together with the wind powder of main burner, it makes methanol purge gas be used to boiler internal, the common completing combustion of coal dust in methanol purge gas and burner, guaranteed the efficient utilization of the energy.
